A memory leak vulnerability in the Linux kernel's MT76 WiFi driver was resolved. The issue involved MT76 receive queues having associated page pools that were not properly destroyed during module unload, leading to resource leakage. This flaw does not impact confidentiality or integrity but can cause availability issues due to resource exhaustion.
AI Analysis
Technical Summary
The CVE-2026-53104 vulnerability in the Linux kernel's MT76 WiFi driver concerns a memory leak caused by improper cleanup of page pools associated with all MT76 receive queues, including those not linked to NAPI (e.g., WED RRO queues with WED enabled). The fix involves destroying the page pools during module unload and returning pages to the pool if WED is not enabled for WED RRO queues, preventing resource leakage.
Potential Impact
The vulnerability has no impact on confidentiality or integrity but can degrade system availability by leaking memory resources during device destruction or module unload, potentially leading to denial of service conditions.
Mitigation Recommendations
A fix for this memory leak has been implemented in the Linux kernel. Users should update to the kernel version that includes this patch to prevent resource leakage. Patch status is not explicitly confirmed in the provided data; therefore, check the vendor or kernel mailing lists for the exact fixed version and apply the update accordingly.
